Manchester United have had an £85m bid for Paul Pogba rejected by Juventus, according to Sky in Italy.
United had the offer turned down on Tuesday but have reportedly been told by the Italian champions that a world-record transfer fee in excess of £100m for the France midfielder would be accepted.
Earlier this week Sky in Italy reported Pogba had already agreed personal terms of a salary of £10.92m (13m euros) a year.
It is understood Juventus have now accepted Pogba wants to leave the club, although the cost of the deal has already priced Real Madrid out of the market.
United's initial offer was made during a meeting between their executive vice-chairman, Ed Woodward, Pogba's agent, Mino Raiola, and Juventus general manager and CEO Giuseppe Marotta.
Pogba remains on holiday and will not return to Turin until August 6.
New United boss Jose Mourinho recently spoke of four priority targets in the transfer window and midfielder Henrikh Mkhitaryan's capture marked their third acquisition following the arrivals of Zlatan Ibrahimovic and centre-back Eric Bailly.
Pogba left Old Trafford on a free transfer in 2012 but the 23-year-old could be set to return this summer, with negotiations over a deal understood to have begun earlier this month.
The United squad are currently in China for their 2016-17 pre-season tour, during which they will play friendly matches against Borussia Dortmund and Manchester City.
Mkhitaryan and Bailly travelled with the squad on Tuesday but Ibrahimovic has not been included on the trip.
